CHUTE-SPRING.

Application filed February 20, 1911.

To all whom, it may concern Be it known that I, Evnnn'rr M. Low, citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Chute-Springs, of which the following is a specification.

My invention relates to that class of devices known as chute springs, which form an important element in the assembling mechanism of the linotype machine and the object of my invention is to provide a chute spring that will act more etliciently than the ones now in use, byavoiding transpositions in the assembled line of matrices and space hands; by preventing the matrices from jumping out of the assembling elevator or choking up in the assembler and by avoiding the wear on the matrices incident to an assembled matrix being struck by the one that 1" )llOYS it in the act of assembling. I attain these objects by the device illustrated in the accompanying drawings in which:

Figure l, is an elevation of the chute spring and so much of the'assembling mecha nism as is necessary toshow, its connection therewith; Fig. 2, is a view of'the chute spring looking in the direction of the arrow y, Fig. 1; Fig. 3, is a view of the matrix, showing the points where the matrices are damaged by the ones following in the act of assembling; Fig. 4, is a view of the chute spring looking in the direction of the arrow Z, Fig. 2.

Similar letters refer to similar parts throughout the several views.

In Fig. 1, the assembler a, is shown with the glass front removed and the assembling elevator I), is shown with the front part removed, the better to show the matrices in the assembling mechanism. The matrices descend the magazine plate f between the guides (2, through the throat d, into the assembling elevator Z), by the action of gravity and the rapidly moving inclined belt 6, atter being released in the usualand well known manner from the magazine which is located above the magazine plate f, and the guides 0. only a part of which are shown. The matrices descend tl'u'ough the throat (I, and as soon as the top 1, of the matrix S, has passed the chute spring A, it is forced forward and downward to a vertical position in the assembling elevator b, by the action of the rapidly revolving star wheel h,

which causes the matrix S, to take its place in the assembling line Z. The space bands j, fall by gravity through the chute has they are released from the space band .box by the usual and well known means. The matrices and space bands are asseii'ibled with great rapidity and frequent transpositions of the matrices and space bands occur owing to the top 5, of the matrix being retarded in the act of assuming a vertical position, thus allowing the space band j, to drop before. the matrix B, has moved far enough forward to be in advance of the descending space band and consequently the space band j, is on the wrong side of the matrix S, or is transposed. The throat (I, must be of such width as to allow the matrices to pass through .l'recly but must not be wide enough to allow the matrices to assume a horizontal position and jump out on the top of the assembling line and the downward extensions 5 1") of the chute spring A, must project far enough toward the assembling elevator I), to prevent the matrices from jumping up "aid and out of the assembling elevator b. The chute springs in use heretofore have the lower end bent at such an angle that it lies in a horizontal plane along the line .22, As the top t, of the matrix S, is forced by the star wheel l1, outward after it passes below the throat plate 8, it moves in a curve and should be free from retardation from the time it leaves its contact with the throat plate 8, until it impinges against the downward extensions 5-5 just above their points.

In the chute springs heretofore in use there is no concavity at (3, and the top t. of the matrix S, is retarded allowing the space band j, to drop ahead instead of behind the matrix, causing a transposition. This retardation of the top t, of the matrix S, causes the lower end 7.. of the matrix to be thrown outward by the-action of the star wheel 11, causing the end 1?, of the matrix S, to strike the matrix '12. in the assembling line at the points '2', 7', wearing away the wall of the matrix and causing burs on the type from the molten metal entering between the matrices, where they are worn away. The free movement of the top t. of the matrix S, under the concavity 6, also prevei'its the matrix from being thrown out of the assembler by the XCtdltliltl( !l and sudden release of the top 1, of the matrix S, as is the case when the chute spring has no concavity 6.

In the chute springs heretofore in use a stop is riveted to the spring at l0, which holds the spring in place by impinging against anoteh in the plate f, and prevent ins: the spring from closing the throat (l, adjusti'nent is made. by bending the spring and there is no independent adjustment for the throat (I, and the lower part of the spring which forms the upper wall of the throat (Z, is a single piece and the prongs are straight and liein a horizontal plane as indicated by the dotted line 01, as.

The chute spring of my improved construction is formed of the member 1, and the member 2, secured to the member 1, at the upper end 3. The member 2, has two prongs 4,-4, under which the top t, of the matrix S, passes, the space bands passing between the prongs i t. The lower end of the member 1, which forms the adjustable throat plate 8, is free below the point 3, and may be moved to or from the heel 7, of the prongs i -4. in order to adjust the width of the throat (I, without changing the position of the downward extensions 55, of the prongs 44-, which should be set as far forward as possible without interfering with the passage of the assembling elevator when it is raised with the assembled line in the act of sending the line to the casting mechanism. The throat plate 8, is held normally against the member 2, by its tension and to move it away from the member 2, and hold it in its adjusted position the member 2, has the horn 9. which may be bent to throw the throat plate 8, away from the member 2, and hold it in any desired position to secure the proper width of the throat d. The throat plate 8, projects below the heel 7, of the prongs 44, forming the concavity 6, to allow the free passage of the top t, of the matrix S, as it moves outward under the act-ion of the star wheel h. This concavity 6, could be secured without the use of the throatplate 8, by cutting away the prongs 1 4, at

the point (3, but I accomplish the same result by projecting the throat plate 8, below the prongs 44. The downward extensions 5 5, are in practice set even with or slightly in advance of the edge of the assembler plate m, and the downward extensions 55, project downward ,far enough to hold the top 1, of the matrix S, from tilting out ward and to p ess the matrix downward into the assembling elevator as it is forced outward by the action of the star wheel h.

The stop 10, is bent at a right angle at 11, and in the form of the letter U, at 12. It is secured to the member 1, by the clip 13, which allows a movement of the stop 10. in the direction of its length thus allowing the chute spring A, to be raised or lowered. This adjustment is made necessary by the narrow notch n, in the plate f, which admits but little movement.

The chute spring A, is held against the stop 10, by the tension of the member 1, the stop ll), serving to limit the movement of the chute spring toward the throat (I.

The chute spring A, is secured to the machill-1' at t). in the usual and well known manner, and as no change has been made in this part of the device, it has therefore not been shown in detail. The tension of the member 1, is justenough to hold the stop 10, against the side of the notch 71, with a slight pressure which allows the chute spring to raise when large matrices pass through the throat (I.

What I claim and desire to secure by Letters Patent is:

1. In a type bar machine having a magazine plate and a matrix chute, a chute spring arranged in juxtaposition to the matrix chute, embodying a throat plate for engaging the matrices as they pass through the throat, forwardly extending prongs arranged to prevent the matrices from jumping upwardly out of the line forming position, means for engaging the magazine plate of the machine to retain the prong member in position. and means for adjusting the relative positions of said throat plate and said prongs whereby the position of the throat plate may be adjusted relatively to the throat and said prongs may be retained in the desired position relative to the line composing devices.
